This is the first time we've done a ported 7670 car, and it definitely makes a difference. Response is definitely a little bit more sluggish( about 300rpms slower), but the peak power is noticeably different. We are working on a video of the car. Its pretty basic;

Large Streetport, FMIC, Stock ignition, full 3" exhaust, Adaptronic FD PNP, Pump gas, our cast 7670 IWG turbo kit, walbro 460lph/ID2000 secondaries etc.

 

 

Cool! I'm not a dyno graph reading expert, but is that graph saying 6.58 psi boost? I wanted to know how much boost the car is running

 

310rwhp sounds about right for a 57mm turbo running 9psi fading to 7psi boost.

Remember the Dyno Dynamics is in "comparison mode" here to simulate Dynojet numbers (adds 15%).

310rwhp Dynojet or 265rwp Dyno Dynamics.

From memory my EFR 7670 did 274rwhp Dyno Dynamiics at 10psi fading to 8psi boost- that is why I say this sounds about right. *bad memory- see edit below*

I had been disappointed in my 7670 low boost results because my 60-1 held 10psi to redline and so did 295 Dyno Dynamics. I was not disappointed when I drove the 7670, it more than made up for the loss in peak with the power under the curve.

-Edit-
No, my posts from 2014 says I was running peak 13psi on my 7670 at 275rwhp, so probably fading down to 8 or 9psi at peak power.

 

Big power for such small boost!
